FIG. 1 is a top view schematically showing the electronic component mounting machine 10. On the base 11 of the electronic component mounting machine 10, a board transfer device 20 that transfers the board S in the Y direction is provided.

  The substrate transport device 20 transports the substrate S in a predetermined direction (left direction in FIG. 1), and includes first and second guide rails 21 and 22 assembled on the base 11. The first and second guide rails 21 and 22 extend in the transport direction and are disposed in parallel with each other, and guide the substrate S in the transport direction. In addition, a pair of conveyor belts provided in parallel to each other are provided in parallel in the substrate transport device 20 immediately below the first and second guide rails 21 and 22. These conveyor belts support the substrate S and transport it in the transport direction. The substrate transport device 20 is provided with a clamping device that pushes up and clamps the substrate S transported to a predetermined position. As a result, the substrate S is carried onto the substrate carrying device 20 and is carried to a predetermined position, positioned and fixed, mounted with electronic components, and then carried out.

  On the upper side of the substrate transfer device 20 (the front side in the direction perpendicular to the paper surface in FIG. 1), a moving base 31 elongated in the Y direction is fixed to a fixed rail (frame) 32 extending in the X direction perpendicular to the Y direction. It is supported movably. The movement of the moving base 31 in the X and Y directions is controlled by a servo motor through a ball screw.

  The electronic component mounting machine 10 includes a control device 13. The control device 13 controls the operations of the substrate transfer device 20, the component transfer device 33, and the component supply device 40.

  On both sides of the electronic component mounting machine 10, a large number of component supply devices 40 are juxtaposed with the substrate transfer device 20 interposed therebetween. As shown in FIG. 2, the component supply device 40 is a component supply device including a tape feeder. A supply reel 42 is rotatably and detachably mounted on the main body 41 of the component supply device 40. A carrier tape 44 that holds a predetermined number of components (electronic components) 43 at a constant pitch interval is wound around the supply reel 42. As shown in FIG. 3, the carrier tape 44 is formed to be elongated with a predetermined width, and in the longitudinal direction of the carrier tape 44, for example, component storage portions 45 made of emboss are provided at regular pitch intervals. The component storage unit 45 stores and holds the components 43 mounted on the circuit board. The opening of the component storage unit 45 is covered by a cover tape 46 attached to the carrier tape 44, and the component 43 is taped by the carrier tape 44 and the cover tape 46. On one end side in the width direction of the carrier tape 44, feed holes 47 are associated with the pitch of the parts 43 and are formed at standardized intervals.

  Although not shown, an identification code is assigned to the side surface of the supply reel 42, and by reading the identification code, the model number and dimensions of the component 43, the number of components 43 held on the carrier tape 44, and the holding pitch Alternatively, it is possible to identify whether the carrier tape 44 is an embossed carrier type or a punch carrier type. The embossed carrier mold is a carrier tape in which a component storage portion 45 is recessed by molding a long thin resin material such as press molding, pressure forming, or vacuum forming. The punch carrier type is a carrier tape in which, for example, a component storage portion 45 is recessed by punching (perforating) a long and thin base paper. In this embodiment, an embossed carrier type carrier tape is used.

A component transfer device 49 and a detection sensor 50 are arranged on the main body 41 of the component supply device 40.
The component transfer device 49 sends out the carrier tape 44 wound around the supply reel 42 one pitch at a time, and transfers the components 43 one by one to a component supply position 48 provided at the tip of the main body 41. The component transfer device 49 includes a guide portion 49a that guides the carrier tape 44 to the component supply position 48, a sprocket 49b that is rotatably supported by the main body 41 and engages with a feed hole 47 of the carrier tape 44, and a sprocket 49b that has one pitch. And a motor (not shown) that rotates minutely. The guide portion 49a is disposed between the detection sensor 50 and the component supply position 48, whereby the carrier tape 44 fed from the supply reel 42 is placed on the conveyance path 49c determined while being guided by the guide portion 49a. Be transported.

  When the sprocket 49b is rotated by one pitch by the motor, the carrier tape 44 is fed by one pitch by the sprocket 49b, and the components 43 stored in the component storage section 45 are supplied to the component supply position 48 one by one. The component 43 supplied to the component supply position 48 is sucked by the suction nozzle 37 of the component transfer device 33, transferred to the mounting position of the component mounting machine, and mounted on the substrate S. The carrier tape 44 from which the component 43 has been taken out is collected below the main body 41, while the cover tape 46 is peeled off before the component supply position 48 and discharged to a predetermined position while being guided by a plurality of rollers 49d. .

  The detection sensor 50 is disposed between the component supply position 48 and the supply reel 42, and first and second detection marks 71 and 72 provided on the carrier tape 44 (first and second carrier tapes 44A and 44B). Is detected. The detection sensor 50 detects the presence / absence of a metal in the object to be inspected based on a change in magnetic field caused by the passage of the object to be inspected. The first and second detection marks 71 and 72 are made of a tape containing a metal material. As a result, the first and second detection marks 71 and 72 are detected by the detection sensor 50. The first and second detection marks 71 and 72 are provided at front and rear positions in the traveling direction across the joint between the first and second carrier tapes 44A and 44B.

  When the remaining amount of carrier tape 44 is reduced, another carrier tape 44 (hereinafter referred to as second carrier tape 44B) is spliced (connected) to carrier tape 44 (hereinafter referred to as first carrier tape 44A). I try to replenish. The first carrier tape 44A is a carrier tape located on the downstream side in the feed direction (advancing direction indicated by arrows in FIGS. 3 and 4), and the second carrier tape 44B is a carrier tape located on the upstream side in the feed direction. . As shown in FIG. 4, the end portion 44A1 of the first carrier tape 44A and the start end portion 44B1 of the second carrier tape 44B are spliced by a splice tape 61 that is a splice member.

  Note that pre-processing will be described in splicing the first carrier tape 44A and the second carrier tape 44B. The unnecessary portion of the first carrier tape 44A where the component 43 is not housed (empty tape portion) is cut, leaving the portion to which the splice tape 61 is attached. At this time, the length to be cut (the length necessary for attaching the splice tape 61) is not defined. The second carrier tape 44B is similarly cut. In the present embodiment, the first carrier tape 44A is cut leaving two empty component storage portions 45 in which no components 43 are stored, and the second carrier tape 44B has three empty component storage portions 45. One is cut off. Thus, since the cutting length (the length of the empty tape portion) is also arbitrary in the pre-processing, it is possible to save the trouble of managing the process.

  The splice tape 61 has an arbitrary length in the feed direction of the carrier tape 44. That is, it is sufficient that the splice tape 61 is long enough to connect the first and second carrier tapes 44A and 44B, and the length is not specified. Therefore, the operator does not need to cut accurately to a specified length, and can cut the splice tape 61 without trouble. Furthermore, the splice tape 61 may be a generally distributed one (for example, an adhesive tape made of vinyl material), and it is not necessary to use a dedicated tape.

  Similarly to the carrier tape 44 (first carrier tape 44A) described above, the second carrier tape 44B has component storage portions 45 formed in the longitudinal direction at the same pitch intervals as the first carrier tape 44A. 45, the same parts 43 are respectively stored and held. Further, feed holes 47 are formed at one end side in the width direction of the second carrier tape 44B at the same pitch interval as the first carrier tape 44A. The opening of the component storage unit 45 is covered with a cover tape 46 attached to the second carrier tape 44B.

  The first carrier tape 44A is provided with a first detection mark 71 as shown in FIG. The first detection mark 71 is a detection mark that can be detected by the detection sensor 50, and is provided at a position indicating the last part of the first carrier tape 44A. In the present embodiment, the first detection mark 71 is composed of an adhesive tape containing a metal material. This adhesive tape is generally used.

  The first detection mark 71 is preferably attached to the side of the component storage portion 45a in which the last component 43a of the first carrier tape 44A is stored. The affixing position is preferably the end on the side where the feed hole 47 is formed. This is because it is easy to stick and erroneous detection by the component 43 can be suppressed. The affixing position may be between the component storage portion 45 adjacent to the upstream side of the component storage portion 45a in which the last component 43a is stored and the component storage portion 45 adjacent to the downstream side.

  The length in the longitudinal direction (feed direction) of the first detection mark 71 is preferably a length that can be accommodated between the feed holes 47 sandwiching the component storage portion 45a. The distance between the feed holes 47 may be longer, but in that case, the tip of the detection mark 61 (the front end in the traveling direction) may be positioned so as to be disposed between the feed holes 47. preferable. Note that the length in the longitudinal direction (feed direction) is such that the component storage portion 45 adjacent to the upstream side of the component storage portion 45a in which the last component 43a is stored and the component storage portion 45 adjacent to the downstream side. A length that fits in between is preferred. The width of the first detection mark 71 is preferably smaller than the width of the end portion where the feed hole 47 is formed, and is preferably smaller than the width of the first carrier tape 44A.

  The first detection mark 71 may be within the range of the above-described conditions. Further, the cut first detection mark 71 can be attached to the first carrier tape 44A without trouble.

  As shown in FIG. 4, the second carrier tape 44 </ b> B is provided with a second detection mark 72 configured similarly to the first detection mark 71. The second detection mark 72 is a detection mark that can be detected by the detection sensor 50, and is provided at a position indicating the first component 43b of the second carrier tape 44B. Specifically, like the first detection mark 71, the second detection mark 72 is attached to the side of the component storage portion 45b in which the first component 43b of the second carrier tape 44B is stored. preferable. The first carrier tape 61 and the second carrier tape 62 do not necessarily have the same shape as long as they are within the above-described conditions, and may have different shapes.

  Next, the splicing method of the above-mentioned spliced carrier tape will be described with reference to FIGS. Using a generally available cutting device (for example, scissors), the portion where the component 43 of the first carrier tape 44A is not stored (empty tape portion) is left unnecessarily, leaving the portion where the splice tape 61 is attached. Disconnect. The second carrier tape 44B is similarly cut. At this time, the length to be cut is not defined and is arbitrary. In the present embodiment, the first carrier tape 44A is cut leaving two empty component storage portions 45 in which no components 43 are stored, and the second carrier tape 44B has three empty component storage portions 45. It has been cut off (see FIG. 3).

  Then, the first detection tape 71 having an appropriate size is attached to the first carrier tape 44A within the range of the above-described conditions, and the second detection tape 72 having an appropriate size is applied to the range of the above-described conditions. It is affixed to the second carrier tape 44B (see FIG. 4). Then, the splice tape 61 is pasted so as to splice the end portion 44A1 of the first carrier tape 44A and the start end portion 44B1 of the second carrier tape 44B (see FIG. 4). The order of attaching the splice tape 61 and the first and second detection tapes 71 and 72 may be reversed.

  Next, a method for feeding the carrier tape spliced by the above-described splicing method will be described with reference to the flowchart shown in FIG.

  When the main power supply (not shown) of the electronic component mounting machine is turned on, the control device 13 repeatedly executes the program according to the flowchart shown in FIG. 5 every predetermined short time. Each flag Fa, Fb, Fc is initialized when the power is turned on.

1) Until the first detection mark is detected Since the flags Fa, Fb, and Fc are cleared to 0 when the power is turned on, the control device 13 is set until the flag Fc is set to 1 (the first detection mark). Until 71 is detected), the determination of “YES”, “YES”, “YES”, and “NO” is repeated in steps 102, 104, 106, and 108.

  In step 110, the control device 13 controls the motor (mounted on the component supply device 40) so as to feed the spliced carrier tape 44 at a predetermined pitch. The predetermined pitch in this embodiment is the same as the pitch between the feed holes 47.

  The flag Fa indicates whether or not the last component 43a of the first carrier tape 44A has reached the component supply position 48 before the second detection mark 72 is detected by the detection sensor 50. The flag Fa is 1, indicating that the second detection mark 72 has been detected by the detection sensor 50 after the last component 43a of the first carrier tape 44A has reached the component supply position 48. It shows that the last component 43a of the first carrier tape 44A has reached the component supply position 48 after the use mark 72 is detected by the detection sensor 50.

  Further, the flag Fb is a flag indicating whether or not derivation of a feed amount, which will be described later, is completed when the second detection mark 72 is detected first. 1 indicates the end of derivation, and 0 indicates before derivation. Or derivation is shown.

  Further, the flag Fc is a flag indicating whether or not the first detection mark 71 has been detected. 0 indicates that it has not been detected yet, and 1 indicates that it has already been detected.

  Hereinafter, after the first detection mark 71 is detected, a point in time when the second detection mark 72 is detected and a point before and after the last part 43a of the first carrier tape 44A reaches the part supply position 48. A description will be given for each case.

2) When the second detection mark is detected first When the detection sensor 50 detects the first detection mark 71, the control device 13 determines “YES” in steps 102, 104, 106, and 108, respectively. Then, derivation of the feed amount (collective feed amount) is started (step 114). At this time, the flag Fc is set to 1 (step 116).

  As the feed amount (collective feed amount), the feed amount of the sprocket 49b from the time when the first detection mark 71 is detected to the time when the second detection mark 72 is detected is derived, and this derived feed amount is collectively fed. It can be derived by taking a quantity. Therefore, in step 114, the feed amount to be derived may be set to 0 and the feed amount count may be started. Further, the feed amount at the time when the first detection mark 71 is detected may be stored.

  Thereafter, since the flag Fc is set to 1 (step 116), the control device 13 determines “NO” in step 106 and causes the program to jump to step 118. The control device 13 repeats the determination of “NO” in step 118 until the detection sensor 50 detects the second detection mark 72.

  If the determination is “NO” in step 118, the control device 13 advances the program to step 120. In step 120, the control device 13 determines whether or not the last component 43 a of the first carrier tape 44 </ b> A has reached the component supply position 48.

  Specifically, in step 120, it is determined that the last component 43a has reached the component supply position 48 as follows. In this embodiment, since the first detection mark 71 is provided beside the last part 43a, the position of the first detection mark 71 is the same as the position of the last part 43a. Therefore, the feed amount of the carrier tape 44 is derived from the time point based on the predetermined pitch with the time point when the detection sensor 50 detects the first detection mark 71 as a reference. If the derived feed amount reaches the distance (known) between the component supply position 48 and the position of the detection sensor 50, it can be determined that the last component 43a has reached the component supply position 48.

  In this case, since the second detection mark 72 is detected before the last component 43a of the first carrier tape 44A reaches the component supply position 48, the control device 13 performs steps "118" and "120" respectively. The determination of “NO” is repeated. Therefore, the control device 13 advances the program to step 110 and controls the motor so as to feed the spliced carrier tape 44 at a predetermined pitch.

  When the second detection mark 72 is detected by the detection sensor 50, the control device 13 determines “YES” in step 118, and ends the derivation of the feed amount (collective feed amount) (step 122). At this time, the flag Fb is set to 1 (step 124). In step 122, the counted feed amount is stored as a batch feed amount, and the count up of the feed amount is completed. The difference between the feed amount at the time when the second detection mark 72 is detected and the feed amount at the time when the first detection mark 71 previously stored may be detected may be stored as a batch feed amount.

  Thereafter, since the flag Fb is set to 1 (step 124), the control device 13 determines “NO” in step 104 and causes the program to jump to step 126. The control device 13 repeats the determination of “NO” in step 126 until it is determined that the last component 43a of the first carrier tape 44A has reached the component supply position 48. The process of step 126 has the same contents as the process of step 120 described above.

  Therefore, if the determination is “NO” in step 126, the control device 13 advances the program to step 110 and controls the motor so as to feed the spliced carrier tape 44 at a predetermined pitch.

  When the control device 13 determines that the last component 43a of the first carrier tape 44A has reached the component supply position 48, it determines “YES” in step 126, and only the feed amount previously derived and stored is determined. The carrier tape 44 is fast-forwarded at a time (step 128). Thereafter, the flags Fb and Fc are reset to 0 (step 130) and the feed amount is also reset to 0 (step 132).

3) When the last component reaches the component supply position first The control device 13 determines that the last component 43a of the first carrier tape 44A is the component supply position 48 before the detection sensor 50 detects the second detection mark 72. Is reached, it is determined as “NO” or “YES” in steps 118 and 120, and the program proceeds to step 134 and thereafter.

  The control device 13 finishes the derivation of the previously started feed amount, clears the feed amount (step 134), and starts the fast feed of the carrier tape 44 (step 136). At this time, the flag Fa is set to 1 (step 138).

  Thereafter, since the flag Fa is set to 1 (step 138), the control device 13 determines “NO” in step 102 and causes the program to jump to step 140. The control device 13 repeats the determination of “NO” in step 140 until the detection sensor 50 detects the second detection mark 72.

  If the determination is “NO” in step 140, the control device 13 advances the program to step 142 and continues fast-forwarding of the carrier tape 44.

  When the second detection mark 72 is detected by the detection sensor 50, the control device 13 determines “YES” in step 140 and advances the program to step 144. In step 144, the control device 13 determines whether or not the first component 43b of the second carrier tape 44B has reached the component supply position 48.

  Specifically, in step 120, it is determined that the first component 43b has reached the component supply position 48 as follows. In the present embodiment, since the second detection mark 72 is provided beside the first part 43b, the position of the second detection mark 72 is the same as the position of the first part 43b. Therefore, the feed amount of the carrier tape 44 is derived from the time point based on the predetermined pitch (pitch of the feed hole) with the time point when the detection sensor 50 detects the second detection mark 72 as a reference. If the derived feed amount reaches the distance (known) between the component supply position 48 and the position of the detection sensor 50, it can be determined that the first component 43b has reached the component supply position 48.

  Specifically, the control device 13 does not determine that the first component 43b of the second carrier tape 44B has reached the component supply position 48 after the time point when the second detection mark 72 is detected by the detection sensor 50. In Steps 140 and 144, “YES” and “NO” are determined, and the fast-forwarding of the carrier tape 44 is continued (Step 142).

  On the other hand, if the control device 13 determines that the first component 43b of the second carrier tape 44B has reached the component supply position 48 after the time point when the second detection mark 72 is detected by the detection sensor 50, step 140 is performed. , 144 respectively determine “YES”, and the fast-forwarding of the carrier tape 44 is terminated (step 146). At this time, the flags Fa and Fc are reset to 0 (step 148).

  It should be noted that the fast-forwarding of the carrier tape 44 was started at a time until it was completed in step 136, but once the second detection mark 72 was detected, the feeding was momentarily stopped, and then immediately re-feeding. May be started.

  When the detection sensor 50 cannot identify the first detection mark 71 and the second detection mark 72, the detection sensor 50 recognizes the first detection mark 71 as the first detection mark 71.

  As is apparent from the above description, in the spliced carrier tape according to the present embodiment, the first carrier tape 44A on the downstream side in the feed direction and the second carrier tape 44B on the upstream side in the feed direction are spliced by the splice member 61. Is done. Further, it is sufficient if the first carrier tape 44A and the second carrier tape can be connected, and the position where the splice member 61 is attached is not specified, so that the splice member 61 can be easily spliced without trouble.

  Further, the spliced carrier tape is provided with a first detection mark 71 provided at a position indicating the last part 43a of the first carrier tape 44A and also indicates the first part 43b of the second carrier tape 44B. A second detection mark 72 provided at a position is provided. Therefore, the position indicating the last part 43a of the first carrier tape 44A, the second position, and the second carrier tape 44A, even if there is no process requiring special management in advance, such as preparing an empty tape in advance by a predetermined length as in the prior art, The position indicating the first part 43b of the carrier tape 44B can be accurately and accurately indicated by setting the detection mark attachment position as a rule.

  Further, when the detection sensor 50 detects the first and second detection marks 71 and 72 thus provided, the position indicating the last part 43a of the first carrier tape 44A and the second carrier tape 44B It is possible to accurately and accurately grasp the distance from the position indicating the first part 43b, that is, the distance of the part where there is no part. As a result, the spliced carrier tape can be appropriately fed based on the distance of the part without the grasped parts.

  Further, the detection mark 70 applied to the carrier tape spliced by the splice member 61 between the first carrier tape 44A on the downstream side in the feeding direction and the second carrier tape 44B on the upstream side in the feeding direction is the first carrier tape 44A. The first detection mark 71 is provided at a position indicating the last part 43a, and the second detection mark 72 is provided at a position indicating the first part 43b of the second carrier tape 44B. Therefore, the position indicating the last part 43a of the first carrier tape 44A, the second position, and the second carrier tape 44A, even if there is no process requiring special management in advance, such as preparing an empty tape in advance by a predetermined length as in the prior art, The position indicating the first part 43b of the carrier tape 44B can be accurately and accurately indicated.

  Further, when the detection sensor 50 detects the first and second detection marks 71 and 72 thus provided, the position indicating the last part 43a of the first carrier tape 44A and the second carrier tape 44B It is possible to accurately and accurately grasp the distance from the position indicating the first part 43b, that is, the distance of the part where there is no part. As a result, the spliced carrier tape can be appropriately fed based on the distance of the part without the grasped parts.

  Further, it is a method of sending the spliced carrier tape as described above (or the component supply device 40), and when the detection sensor 50 provided in the component supply device 40 detects the first detection mark 71 ( If “YES” is determined in step 108), the carrier tape 44 is predetermined until the last component 43 a of the first carrier tape 44 A reaches the component supply position 48 (until “YES” is determined in step 126). When the last part 43a of the first carrier tape 44A reaches the part supply position 48, the feed amount is the same as the distance between the first detection mark 71 and the second detection mark 72 (step 110). Fast feed is performed (until the first part 43b of the second carrier tape 72 reaches the part supply position 48) (step 128, step). 138,142,146), then sends back a predetermined pitch (step 110). Accordingly, the detection sensor 50 detects the first and second detection marks 71 and 72, so that the position indicating the last part 43a of the first carrier tape 44A and the first part 43b of the second carrier tape 44B are detected. It is possible to accurately and accurately grasp the distance from the indicated position, that is, the distance of the part where there is no part. As a result, the spliced carrier tape can be appropriately fed based on the distance of the part without the grasped parts.

  In the present embodiment, the distance between the first detection mark 71 and the second detection mark 72 is the distance between the centers of the marks 71 and 72. Not the center distance, but the distance between the inner end of the first detection mark 71 (end on the second detection mark 72 side) and the inner end of the second detection mark 72 (end on the first detection mark 71 side). It may be a distance.

  In addition, after the first detection mark 71 is detected by the detection sensor 50 and before the second detection mark 72 is detected by the detection sensor 50, the last part 43a of the first carrier tape 44A is the part. When the supply position 48 is reached, when the last part 43a of the first carrier tape 44A reaches the part supply position 48 (determined as “YES” in step 120), the detection sensor 50 starts the second detection from that point. Until the mark 72 is detected (determined as “YES” in step 140), the carrier tape 44 is fast-forwarded (steps 136 and 142), and when the detection sensor 50 detects the second detection mark 72 (“140” in step 140). YES ”), the first component 43b of the second carrier tape 44B reaches the component supply position 48 from the detection time (step Further fast-forward to determine) a "YES" in-flop 144 (step 142, 146). Thereby, when the distance between the component supply position 48 and the detection position by the detection sensor 50 is shorter than the distance between the first detection mark 71 and the second detection mark 72, the spliced carrier tape Can be controlled appropriately.

  The second detection mark 72 is detected after the first detection mark 71 is detected by the detection sensor 50 and before the last component 43a of the first carrier tape 44A reaches the component supply position 48. When detected by the sensor 50, the first and second detected by the detection sensor 50 are detected when the second detection mark 72 is detected by the detection sensor 50 (determined as “YES” in step 118). A distance (feed amount) is derived based on the detection information of the detection marks 71 and 72 (step 122), and when the last component 43a of the first carrier tape 44A reaches the component supply position 48 (“YES” in step 126). "Determined") as much as the distance (feed amount) between the derived first detection mark 71 and second detection mark 72 (the first portion of the second carrier tape 72). 43b until it reaches the component supply position 48) to fast-forward the carrier tape (step 128). Thereby, when the distance between the component supply position 48 and the detection position by the detection sensor 50 is longer than the distance between the first detection mark 71 and the second detection mark 72, the spliced carrier tape Can be controlled appropriately.

  After the first detection mark 71 is detected by the detection sensor 50, the second detection mark 72 is detected by the detection sensor 50 before the last component 43a of the first carrier tape 44A reaches the component supply position 48. Is detected, the distance between the first detection mark 71 and the second detection mark 72 is derived based on the detection results of the first and second detection marks 71 and 72, and the first carrier tape 44A Fast feed is performed by a distance derived from the time when the last component 43a reaches the component supply position 48, while the second detection mark 72 is detected by the last sensor of the first carrier tape 44A before being detected by the detection sensor 50. When the component 43a reaches the component supply position 48, the second detection is performed from the time when the last component 43a of the first carrier tape 44A reaches the component supply position 48. Control can be made so that fast-forwarding is performed until the first part 43b of the second carrier tape 44B, which is determined based on the time when the mark 72 is detected by the detection sensor 50, reaches the part supply position 48. .

  In the above-described embodiment, the first detection mark 71 is affixed to the side of the component storage portion 45a in which the last component 43a of the first carrier tape 44A is stored, and the second detection mark 72 is the second detection mark 72. The first tape 43B is affixed to the side of the component storage portion 45b in which the first component 43b of the carrier tape 44B is stored (see FIG. 4). As shown in FIG. 6, the first detection mark 71 is attached to the first carrier tape. 44A is pasted to the side of the empty component storage portion 45c positioned first in the traveling direction of 44A, and the second detection mark 72 is placed beside the empty component storage portion 45d positioned last in the traveling direction of the second carrier tape 44B. You may make it stick to. In this case, the periphery of the empty component storage portion 45c positioned first in the traveling direction of the first carrier tape 44A is a position indicating the last component of the first carrier tape 44A. The periphery of the empty component storage portion 45d located at the end of the second carrier tape 44B in the traveling direction is a position indicating the first component of the second carrier tape 44B. Further, in this case, the batch feed amount needs to be corrected by the pitch of the component storage portion 45 at the front and rear ends of the empty tape portion.

  In the above-described embodiment, the first and second detection marks 71 and 72 are made of an adhesive tape containing a metal material, and the detection sensor 50 is made of metal that can detect metal. However, the first and second detection marks 71 and 72 may be configured by punch holes, and the detection sensor 50 may be configured by a detection device (for example, a reflective optical sensor) that detects the punch holes. Moreover, you may make it use a metal member (for example, a stapler, a rivet) instead of the adhesive tape containing a metal material.

  In the above-described embodiment, the splice member is a splice tape made of an adhesive tape, but other connection members (for example, staples) may be used.

  In the present embodiment, the position of the detection sensor 50 may be arranged upstream of the component supply position 48.
